General Information
Cleaning Optical Connectors
Cleaning Optical Connectors
Accurate and repeatable measurements require clean connections. Use the following guidelines
to achieve the best possible performance when making measurements on a fiber-optic system:
• Keep connectors covered when not in use.
• Use dry connections whenever possible.
• Use the cleaning methods described in this section.
• Use care in handling all fiber-optic connectors.
• When inserting a fiber-optic connector into a front-panel adapter, make sure that the fiber end
does not touch the outside of the mating connector or adapter.
Because of the small size of cores used in optical fibers, care must be used to ensure good connections. Poor connections result from core misalignment, air gaps, damaged fiber ends, contamination, and improper use and removal of index-matching compounds.
Use dry connections. Dry connectors are easier to clean and to keep clean. Dry connections can
be used with physically contacting connectors (for example, Diamond HMS-10/HP, FC/PC,
DIN, and ST). If a dry connection has 40 dB return loss or better, making a wet connection will
probably not improve, and can actually degrade, performance.
CAUTION
Agilent Technologies strongly recommends that index matching compounds not be applied to
their instruments and accessories. Some compounds, such as gels, may be difficult to remove and
can contain damaging particulates. If you think the use of such compounds is necessary, refer to
the compound manufacturer for information on application and cleaning procedures.

Inspecting Fiber-Optic Cables
Consistent measurements with your lightwave equipment are a good indication that you have
good connections. However, you may wish to know the insertion loss and/or return loss of your
lightwave cables or accessories. If you test your cables and accessories for insertion loss and
return loss upon receipt, and retain the measured data for comparison, you will be able to tell in
the future if any degradation has occurred.
Connector (or insertion) loss is one important performance characteristic of a lightwave connector. Typical values are less than 0.5 dB of loss, and sometimes as little as 0.1 dB of loss with high
performance connectors. Return loss is another important factor. It is a measure of reflection: the
less reflection the better (the larger the return loss, the smaller the reflection). The best physically
contacting connectors have return losses better than 50 dB, although 30 to 40 dB is more common.
Visual inspection of fiber ends
Although it is not necessary, visual inspection of fiber ends can be helpful. Contamination or imperfections on the cable end face can be detected as well as
cracks or chips in the fiber itself. Use a microscope (100X to 200X magnification) to inspect the entire end face for contamination, raised metal, or dents in
the metal as well as any other imperfections. Inspect the fiber for cracks and
chips. Visible imperfections not touching the fiber core may not affect performance (unless the imperfections keep the fibers from contacting).
1-5
General Information
Cleaning Optical Connectors
To clean a non-lensed connector
CAUTION
Do not use any type of foam swab to clean optical fiber ends. Foam swabs can leave filmy deposits
on fiber ends that can degrade performance.
1 Apply isopropyl alcohol to a clean, lint-free cotton swab or lens paper.
Cotton swabs can be used as long as no cotton fibers remain on the fiber end after cleaning.
2 Before cleaning the fiber end, clean the ferrules and other parts of the connector.
3 Apply isopropyl alcohol to a new, clean, lint-free cotton swab or lens paper.
4 Clean the fiber end with the swab or lens paper. Move the swab or lens paper back and forth across
the fiber end several times.
Wiping or mild scrubbing of the fiber end can help remove particles when application of alcohol
alone will not remove them. This technique can remove or displace particles smaller than one micron.
5 Immediately dry the fiber end with a clean, dry, lint-free cotton swab or lens paper.
6 Blow across the connector end face from a distance of 6 to 8 inches using filtered, dry, compressed
air. Aim the compressed air at a shallow angle to the fiber end face.
Nitrogen gas or compressed dust remover can also be used.
CAUTION
Do not shake, tip, or invert compressed air canisters, because this releases particles in the can into
the air. Refer to instructions provided on the compressed air canister.
7 As soon as the connector is dry, connect or cover it for later use.

General Information
Cleaning Optical Connectors
To clean an adapter
1 Apply isopropyl alcohol to a clean foam swab.
Cotton swabs can be used as long as no cotton fibers remain after cleaning. The foam swabs listed
in this section’s introduction are small enough to fit into adapters.
Although foam swabs can leave filmy deposits, these deposits are very thin, and the risk of other
contamination buildup on the inside of adapters greatly outweighs the risk of contamination by
foam swabs.
2 Clean the adapter with the foam swab.
3 Dry the inside of the adapter with a clean, dry, foam swab.
4 Blow through the adapter using filtered, dry, compressed air.
Nitrogen gas or compressed dust remover can also be used. Do not shake, tip, or invert compressed air canisters, because this releases particles in the can into the air. Refer to instructions
provided on the compressed air canister.

General Information
Electrostatic Discharge Information
Electrostatic Discharge Information
Electrostatic discharge (ESD) can damage or destroy electronic components. All work on electronic assemblies should be performed at a static-safe work station. The following figure shows
an example of a static-safe work station using two types of ESD protection:
• Conductive table-mat and wrist-strap combination.
• Conductive floor-mat and heel-strap combination.
Both types, when used together, provide a significant level of ESD protection. Of the two, only
the table-mat and wrist-strap combination provides adequate ESD protection when used alone.
To ensure user safety, the static-safe accessories must provide at least 1 MΩ of isolation from
ground. Refer to Table 1-4 for information on ordering static-safe accessories.

If the instrument is still under warranty or is covered by an Agilent maintenance contract, it will
be repaired under the terms of the warranty or contract (the warranty is at the front of this manual). If the instrument is no longer under warranty or is not covered by an Agilent maintenance
plan, Agilent Technologies will notify you of the cost of the repair after examining the unit.
When an instrument is returned to an Agilent Technologies service office for servicing, it must
be adequately packaged and have a complete description of the failure symptoms attached. When
describing the failure, please be as specific as possible about the nature of the problem. Include
copies of additional failure information (such as the instrument failure settings, data related to
instrument failure, and error messages) along with the original calibration data disks and the
instrument being returned.
Preparing the instrument for shipping
1 Write a complete description of the failure and attach it to the instrument. Include any specific
performance details related to the problem. The following information should be included with
the instrument being returned for service:
• Type of service required.
• Date instrument was returned for repair.
• Description of the problem:
• Whether problem is constant or intermittent.

1-11
General Information
Returning the Instrument for Service
CAUTION
Cover electrical connectors to protect sensitive components from electrostatic damage. Cover
optical connectors to protect them from damage due to physical contact or dust.
CAUTION
Instrument damage can result from using packaging materials other than the original materials.
Never use styrene pellets as packaging material. They do not adequately cushion the instrument
or prevent it from shifting in the carton. They may also cause instrument damage by generating
static electricity.
3 Pack the instrument in the original shipping containers. Original materials are available through
any Agilent Technologies office. Or, use the following guidelines:
• Wrap the instrument in antistatic plastic to reduce the possibility of damage caused by electrostatic discharge.
• For instruments weighing less than 54 kg (120 lb), use a double-walled, corrugated cardboard
carton of 159 kg (350 lb) test strength.
• The carton must be large enough to allow approximately 7 cm (3 inches) on all sides of the
instrument for packing material, and strong enough to accommodate the weight of the instrument.
• Surround the equipment with approximately 7 cm (3 inches) of packing material, to protect the
instrument and prevent it from moving in the carton. If packing foam is not available, the best
alternative is S.D-240 Air Cap™ from Sealed Air Corporation (Commerce, California 90001).
Air Cap looks like a plastic sheet filled with air bubbles. Use the pink (antistatic) Air Cap™ to
reduce static electricity. Wrapping the instrument several times in this material will protect the
instrument and prevent it from moving in the carton.
4 Seal the carton with strong nylon adhesive tape.
5 Mark the carton “FRAGILE, HANDLE WITH CARE”.
6 Retain copies of all shipping papers.

Serial Number: US4106 and below
On early DCA mainframes, the LS-120 disk drive would occasionally experience difficulty with
read and write operations.
A new ground connection was added on the A16 LS-120 Adapter Board Assembly. Replace the
A16 (part number 86100-66505) with the newer assemblies. Some DCAs may have already
received this modification; refer to Figure 4-15 on page 4-13. The new board assemblies have a
large ground trace added to the connector.
Refer to ”LS-120 Disc Drive Modification (86100A Only)” on page 4-12 as applicable.
Intermittent Problems
with Vertical
Calibrations or
Vertical Trace
Service Note 86100A-03
Serial Number: US4032 and below
On early DCA mainframes, the PLDs on the A13 Acquisition Assembly would occasionally go
into a write mode on power up. This will cause various symptoms such as vertical cal failure,
vertical trace at top or bottom screen, and loss of control of the vertical trace. Sometimes the
DCA fails to completely boot up leaving just the splash screen and the DCA buttons displayed.
Rebooting the DCA fixes the problem. If the DCA boots up properly, the problem will not
appear again.
Installing a PLD header plug on a connector on the A13 Acquisition Assembly can solve the
PLD lockup problem.
Refer to ”A13 Acquisition Board PLD Header Modification (86100A Only)” on page 4-36 as
applicable.

Plug-in Modules Not
Recognized by the
DCA Mainframe
Service Note 86100A-04
Serial Numbers below US4017:
On early DCA mainframes, some modules are not recognized by the DCA. Usually the problem
occurs when a clock recovery module is installed together with another module.
Various modifications were performed on the A13 Acquisition board assembly to solve this
problem. The modifications are not possible in the field.
To determine whether the A13 Acquisition board assembly has been modified, remove it from
the mainframe and examine U55 (see Figure 1-1). If U55 is a Motorola part, the board assembly
has not been modified and must be replaced.
Figure 1-1. U55 location
Replace the entire A13 Acquisition board assembly with the A13 exchange assembly. DCAs
with option 001 (divided trigger) will need to have the option 001 replacement assembly. Look at
the serial tag on the rear panel to see if option 001 is installed.
Refer to ”To Remove the A13 Acquisition (Option 001)” on page 4-32 as applicable.

Performance Verification
This chapter documents the performance tests. Equipment required for individual tests is listed in
the test descriptions in this chapter. Equipment satisfying the critical specifications listed may be
substituted for the recommended model.
Performance Testing
Interval
The performance test procedures may be performed for incoming inspection of the instrument
and should be performed periodically thereafter to ensure and maintain peak performance. The
recommended test interval is yearly or every 2,000 hours of operation.
Specifications
The specifications that apply to a particular test are listed in chapter 1 of this manual. Refer to the
86100A/B on-line help for specifications.
Performance Test
Record
You may record the results of the performance tests in the Performance Test Record provided at
the end of this chapter. The Performance Test Record lists the performance tests and provides an
area to mark test results. You can use the results recorded at incoming inspection for later comparisons during periodic maintenance, troubleshooting, and after repairs or adjustments.
Before Testing
• Warm up the system for at least 60 minutes prior to beginning the performance tests.
• After sufficient warm up, perform a vertical calibration on the system.
• Avoid damage to plug-in front panel connectors. Use 2.4 mm and 3.5 mm connector savers. These
connector savers are a supplied accessory.
• Minimize connector swapping during the procedures to avoid connector wear. All connectors on
test tools and adapters should be inspected both visually and mechanically every few calibrations.
• All connectors should be clean and undamaged to ensure accurate measurements. All 2.4 mm and
3.5 mm connectors should be mechanically and visually checked before inserting any calibration
test tool into them. Damaged connectors or loose connectors may cause the performance verification tests to fail.
• Avoid sharp bends in 2.4 mm, 3.5 mm, SMA, and optical cables. When mating 2.4 mm to 2.4 mm
or 3.5 mm to 3.5 mm, torque all connections to 8 in/lbs. When mating 3.5 mm to SMA or SMA
to SMA, torque all connections to 5 in/lbs.
CAUTION
The module inputs are very sensitive to static discharge. Failure to observe proper antistatic
procedures may damage the gallium arsenide samplers. ESD damage is not covered under the
warranty. All maintenance or operation should be performed with an antistatic mat and wrist strap.
Refer to “Electrostatic Discharge Information” on page 1-9 for further information.
CAUTION
Electrostatic discharge can seriously damage the module’s electrical inputs. To eliminate any
electrostatic build up from a cable you’re connecting to the module, connect a female short to
either end of the cable. Touch the short to an input connector hex nut on the module to discharge
any static build up to ground. Remove the short. Use this procedure for all cables before
connecting them to the module.

Jitter Performance Test
Jitter Performance Test
Jitter is measured at 2.5 GHz with the triggering level adjusted for optimum trigger. The jitter
test measures the oscilloscope’s internal jitter on a 2.5 GHz sine wave. The instrument’s jitter is
less with fast rise time input signals.
A 24 ns delay line is added to delay the input signal so that the trigger point is on screen. The
delay setting is determined and used to calculate the specification limit. A histogram is used to
increase the accuracy of the RMS jitter measurement.
NOTE
The 86100A/B DCA has an additional 2 ns of delay compared to the Agilent 83480A or

Adjustments
This chapter provides adjustment procedures for the Agilent 86100A/B Infiniium DCA Mainframe. Equipment required for individual adjustments is listed in the adjustment descriptions in
this chapter. Equipment satisfying the critical specifications listed may be substituted for the recommended model.
Adjustment Interval
The adjustment procedures should be performed yearly or after every 2,000 hours of operation.
Before Adjusting
• Warm up the system for at least 60 minutes prior to beginning the adjustments.
• Avoid damage to plug-in front panel connectors. Use 2.4 mm and 3.5 mm connector savers. These
connector savers are a supplied accessory.
• Minimize connector swapping during the procedures to avoid connector wear. All connectors on
test tools and adapters should be inspected both visually and mechanically every few calibrations.
• All connectors should be clean and undamaged to ensure accurate measurements. All 2.4 mm and
3.5 mm connectors should be mechanically and visually checked before inserting any calibration
test tool into them. Damaged connectors or loose connectors may cause the performance verification tests to fail.
• Avoid sharp bends in 2.4 mm, 3.5 mm, SMA, and optical cables. When mating 2.4 mm to 2.4 mm
or 3.5 mm to 3.5 mm, torque all connections to 8 in/lbs. When mating 3.5 mm to SMA or SMA
to SMA, torque all connections to 5 in/lbs.
CAUTION
The module inputs are very sensitive to static discharge. Failure to observe proper antistatic
procedures may damage the gallium arsenide samplers. ESD damage is not covered under the
warranty. All maintenance or operation should be performed with an antistatic mat and wrist strap.
Refer to “Electrostatic Discharge Information” on page 1-9 for further information.
CAUTION
Electrostatic discharge can seriously damage the module’s electrical inputs. To eliminate any
electrostatic build up from a cable you’re connecting to the module, connect a female short to
either end of the cable. Touch the short to an input connector hex nut on the module to discharge
any static build up to ground. Remove the short. Use this procedure for all cables before
connecting them to the module.

In this section, you’ll find tables that identify each mechanical and electrical assembly in
the Agilent 86100B mainframe. An Agilent part number is provided for each available part.
NOTE
The 86100A is shown in some of the following identification diagrams. Although some of
the components are not the same as the 86100B, part and assembly locations are virtually
identical.
Part Ordering Information
Only major assemblies can be replaced. To order an assembly, quote the Agilent part number, and indicate the quantity required.
Assemblies can be ordered from the nearest Agilent office. Customers within the USA can
also use either the direct mail-order system or the direct phone-order system described
below. The direct phone-order system has a toll-free phone number available.
Direct Mail-Order System
Within the USA, Agilent can supply parts through a direct mail-order system. Advantages
of using the system are as follows:
• Direct ordering and shipment from Agilent
• No maximum or minimum on any mail order. (There is a minimum order amount for parts
ordered through a local Agilent office when the orders require billing and invoicing.)
• Prepaid transportation. (There is a small handling charge for each order.)
• No invoices
To provide these advantages, a check or money order must accompany each order. Mailorder forms and specific ordering information are available through your local Agilent
office.
Direct Phone-Order System
The toll-free phone number, (800) 227-8164, is available Monday through Friday, 6 am to
5 pm (Pacific time). Regular orders have a 4-day delivery time.
